Study of a Novel High-Density Module with Triangled Light Redirecting Ribbons

Abstract Light redirecting ribbons (LRR) have recently been applied in high-density crystalline silicon modules in PV industry. The adoption of this LRR may bring additional reliability risk, which may probably lead to higher power loss after aging. Therefore, damp heat (DH), thermal cycle (TC), UV irradiation and humidity freezing (HF) test were employed in this work to investigate the reliability of LRR-based high-density crystalline silicon modules. The obtained results show that this novel high-density modules with specially designed triangle ribbons have outstanding reliability both in damp heat and dry heat environment as well as under UV irradiation.
